T all whom 'it may concer/n: y Be it lknown that I, WILLIAMy S. HAMM, a citizen of the Unitedv States, and resident of Hubbard Woods, county of Cook, and State of Illinois, have invented certain new and luseful Improvements in Doors, of which the following is a specification, and which are illustrated in the accompanying drawings, forming a part thereof.

n The invention relates particularly to sheety metal doors, though as to some of its features it might be applied to doors made of other material without departing from its scope. The object of the invention is to provide means for supporting the case of a mortise lock or latch and it consists of a structure such as hereinafter 'described and in which two preferred forms of embodiment are illustrated in the accompanying drawings in which;-

Fig. 1 is a detail edge view of the door;

Fig. 2 is a sectional detail on the line 2-2 of Fig. 1; y

Fig. 3n is a sectional detail on the line 3 3 of Fig. 2;

Fig. 4 is a view similar to Fig. y1, showing the modified form of construction;

Fig. 5 is a sectional detail on the line 5-5 of Fig. 4, and

' 30 Fig. 6 is a sectional detail on the line 6-6 of Fig. 5, the latching element being omitted. In sheet metal doors, particularly such as are now coming into common use in railway cars, it is desirable to use a, latch of the mortise type and it is important that such latch shall be applied'with a minimum cutting away or aperturing of the edge and side walls `of the door. It is further desirable to provide means for securing the latch casing without depending upon screws for that `purpose and also without throwing upon the latch controlling spindle the dutyv of sustaining the force of jars incident to service;` These various objects` are secured by the present invention. v

The side Walls of a sheet metal door are shown in the drawings at 10,11, and its edge wall at 12. These various walls may be secured together in any preferred manner and, as this present invention is not concerned withi this feature of the door, such securing means are notillustrated.

The latching dog 13 is shown as of the pivoted type and as being carried by a casing 14 which' is inserted through an aperture inthe edge of the ydoor proportioned and configured to insurea snug fit ofthe endl plate ofthe casing therein. The usual spindley for controlling.Iy the latch dog-is shown at 15 and to its ends are applied suitable handles 16, 17, of any preferred form.v

At 18, 19, there are shown a pair of escutcheon platesiwhich are fitted against the Side walls of the door and are preferably, `secured together` by means of screws 20 entered into or through a pair of abutting posts 21, 22, formed respectively upon the two escutcheon plates and projecting into suitable apertures in the door walls.

In the construction shown in Figs. 1, 2 and 3 a sheet metal strap 23 formed into a loop, which will snugly receive the latch casing, is secured within the chamber of the door by means of screws or rivets, as 24, setting through the edge wall of the door and outwardly turned ends 25, 26, of the' strap. The length of the loop 23 is such that the inner end of the casing makes contact lwith it ywhen the casing is properly positioned and its width s such that the side margins of the casing bear against each of its side members whereby the casing is supported and is prevented from displacement either vertically or horizontally, the spindle 15 holding it against outward movement. The latch casing is preferably pro vided at its inner end with one or more lugs, as 27, adapted to bear against the (inner face of one of the side walls of the oor.

In the construction illustrated in Figs. 4,`

so far as I am at present advised, the most desirable forms for the invention, it may be variously embodied, the most essential feature being the provision of the shelf for supporting the latch casing.

I claim as my invention:

1. A hollow door adapted to receive a mortise-latch easing, and having a shelfv y metal loop secured Wit-h Such opening for supporting such casing and limiting its inward and upward movements.

5. A ohamfbered sheet metal door having an opening for receiving a latch easing, and a sheet metal loop into which the casing Will fit, the ends of the loop being secured to the side edge of the door.

6. A hollow metal door having side and edge walls7 the edge wall being apertured to receive a mortise-la-tch casing; and a metal loop having its ends secured to the edge Wall of the door and its body portion enclosing the aperture andbeing of such size as to receive the latch casing.

WILLIAM S. HAMM.
